Waist-deep floodwaters caused cars to stall in the middle of highways. People walked due to lack of public transport and impassable traffic. Residents were forced to stay on the rooftops of their houses due to submerged first- or second-floors. A number of people are reported dead or missing.

Here are some pictures and videos we gathered online showing the impact of typhoon Ondoy.

Typhoon Onday Demolishes Eastwood Manila

I spent various parts of the weekend and thanks to Youtube was able to see the real videos people were sending from various parts of of Luzon. My real concern was I didnt see any government agency operating in any of the videos.

Rescue teams are stepping up efforts to reach flood victims in the Philippines, where at least 72 people are feared to have died following torrential rains.

Tropical Storm Ketsana triggered the worst flooding in decades in the capital Manila and nearby provinces.

Defence Secretary Gilbert Teodoro said troops, police and civilian volunteers had rescued more than 4,000 people – many clinging to each other on roofs.

More than 250,000 have been driven from their homes, officials say.

Correspondents say the massive rescue was set to intensify as the weather began to clear and floodwaters began to recede on Sunday.

But some reports estimate that 80% of the capital is still under water.

The government has
declared a "calamity" in Manila and 25 provinces, allowing access to emergency funds.

Some residents have emailed the BBC with their experiences. Lovely Lansang in Marikina says: "I am currently seeking refuge in a shopping centre. Many people are stuck either on their roofs or in the second storey of their houses due to the floods.

"The city is also without clean water and electricity. Right now, I am still in the shopping centre because the roads here are impassable," the email adds.

Appeal for calm

The equivalent of a whole month’s rain fell in six hours as Ketsana, also known as Ondoy, lashed the island of Luzon.

On Saturday, TV images showed gushing water turning roads into rivers, with floods chest-deep and rising.

Philippines President Gloria Arroyo appealed for donations and called for calm.

"I am calling on our countrymen, especially residents of metro Manila and other provinces in the path of the typhoon, to please stay calm, follow the instructions of local officials and civil defence authorities," she said in a TV message on Saturday.

Also on Saturday, Mayor Mon Ilagan of the town of Cainta, in Rizal province to the north, told local media his town was "almost 100% under water".

Rizal Governor Casimiro Ynares was quoted by local media as saying other towns were completely inundated.

Roads leading into Manila were rendered impassable by stalled vehicles, and some ferry services were cancelled.

The Philippines chief weather forecaster has blamed climate change for the downpours that saw 40cm (16in) of rain fall on Manila in a single day.

Thousands of passengers were stranded as international and domestic airports were shut down.

Ketsana, with winds of up to 100km/h, is expected to head out over the South China Sea on Sunday and Monday.
